StorPool – the advanced alternative to Dell PowerFlex
How StorPool compares to Dell PowerFlex (formerly ScaleIO & FlexOS)
From all the block-level Software-Defined Storage (SDS) solutions on the market, Dell/EMC PowerFlex is the closest to StorPool, in terms of high-level capabilities.
In our view, the ex-ScaleIO team was the only one on the market, besides StorPool, who had a very good understanding of the problems with the traditional storage architecture. They also took the hard, but right approach to develop a solution from the ground-up, however their team did allow for some architectural flaws.
On a very high-level the two solution look similar, however the inner workings of StorPool and PowerFlex (ScaleIO) are very different. The performance and scalability metrics are similar, however there are several very important differences in the capabilities of the two products and the way they handle data and how they achieve data consistency, protection and availability.
We have not spent a lot of time on exploring PowerFlex/FlexOS/ScaleIO iterations, but some of the more fundamental differences (without any claims for thoroughness) are:
1. Data integrity:
StorPool does full end-to-end data integrity from the Client/initiator. This is unmatched by any other solution we have seen on the market.
2. Data Versioning:
Unlike PowerFlex/FlexOS/ScaleIO, StorPool keeps a version for every piece of data in the system. In this way if a drive or server fail, we know which is the last copy of the data and use it. This makes StorPool the most reliable storage system on the market with statistical mean time between failure of over 15 years!
In StorPool the user of the system can set the number of copies 1-2-3 (3 copies recommended for production workloads, which is the golden standard for a fast distributed system). We can also do near-zero impact Erasure Coding. In contrast, PowerFlex is fixed to 2 copies only.
4. Pay-per-use Licensing:
StorPool is coming with a cloud-like pricing – on a consumption based, per TB used billing model. However we can still cover CapEx options, unlike any other solution on the market.
5. Storage as a Service (STaaS) with a bring you own standard server model:
StorPool is a software only solution, plus a Fully Managed Service. With StorPool our license fee covers not only all of our extensive feature set, but also all services, so you can have a system up and running all the time (24/7 Enterprise-grade support, SLA /Service Level Agreement/, system design, monitoring, upgrades, patches, etc.).
Also unlike any other solution on the market we keep things simple and provide all functionality and services in one package. No extra cost to unlock features, no extra cost for support & SLA).
